ELEOTBIQALLY-HEATED DISPLAY CABINET.

Application filed April 8, 1921. Serial No. 459,567.

To all whom it may co neevm."

Be it known that 1,. WILLIAM L. BROWN, a citizen of the United Statesand resident of Wichita, in the county of edgwick and State of Kansas,-have invented certain new and useful Improvements in Electrically-Heated Display Cabinets, of which the following is a specification.

My invention relates to electrically heated cabinets for holding anddisplaying peanuts, chestnuts, or other edibles that are intended to bekept and sold in allot condition. The object is to provide a heatedcabinet that will display the goods, protect them from dust, and keepthem heated to a practically uniform temperature. By employingelectricity as the heating agent, I avoid the inconvenience, ba-d odor,and extra cabinet space that would be caused by the use of a fuelburner.

Referring to the accompanying drawings: Fig. 1 is a rear elevation of ac-abinetembodying my invention, portions of the door being broken out toexpose the heating element and one of the lights; Fig. 2 is a diagram ofthe electrical connections in the cabinet; Fig. 3 is a sectional planview taken on line IIIIII of Fig. 1, breaking a portion of theperforated heater shield; Fig. 4

is another section on line 111, viewed upwardly.

The cabinet as shown comprises the base 1, the corner posts 2, andthetop 3. The bottom plate 1 is wood, and is covered. by a sheet metalplate 4, having its edges upturned on three sides, forming flanges 4"(Fig. 3). a

The posts 2 are grooved for holding the edges of glass walls 5, whichform the front and two sides of the cabinet. A door frame 6 is mountedon hinges 7 between the rear posts 2, and is fitted with a glass pane 8,and a latch 9 which holds the door in closed position.

The top 3 is secured to the posts 2 either fixedly or removably. Mountecentrally on said top is a translucent dome 10 which covers an electriclamp 12 (indicated). A second electric lamp 14 is mounted on the lowerside of the top 3, for illuminating the interior of the cabinet. The toplight 12 ismainly for advertising purposes.

15 denotes a glass shelf, supported by brackets 16 (Fig. 3). This shelfforms a convenient support for the commodity being sold after the samehas been placed in sacks.

shown.

An electric heating element 17, Fig. 3, is placed on the bottom plate 4,though the conducting wire, if bare, will, of course, be insulated fromsaid plate the latter being metal. a

With this heater continuously energized, the temperature of the air inthe cabinet would soon become too high, except in very cold weather. Inorder to hold the inside temperature below an excessive degree, Ipurpose to employ a make-and-break thermostat, connecting same in serieswith the heating element and with a source of electric current.Preferably, I locate the thermostat, marked 18, at the top of thecabinet; Fig. 4 showing it as secured to the to plate 3.

he connections are diagrammed on Fig. 2,

in which the two wires 19 represent a lamp cord connected with acommercial lighting circuit. The wires supplying the thermostat 18 andthe heater 17, are connected as Thus the operation of the heater will beunafiected by the condition of the lamps 12, 14 as to on or off.

When the temperature becomes too high, the thermostat will open theheater circuit and will hold the same open until the temperature hasfallen to the point for which the thermostat has been adjusted; when thecircuit will be re-closed and the heating process resumed.

Preferably, the top of the cabinet is to be without openings, exceptingthe small holes made to'pass the electric cord 19 into the cabinet.

As shown on Fig. 3, a suitable shield 20 is secured to the base over theheating element, for holding the nuts from contact with the heatingelement. This shield is perforated, as shown at 21, to permitcirculation of air through the shield. s

The loose nuts are placed upon the bottom plate to a depth of severalinches. They will in time become uniformly heated from the heatingelement 17. Sacks filled with the nuts are laid on the shelf 15, wherethey will be kept hot and ready for dispensing.

The entire metal plate 4, upon which the heating'elemcnt rests, will beraised in temperature by heat emitted by the heater 4, and said platewill thus constitute an extended heating surface whereby the nuts notdirectly above the element 4- will be heated.

Having now described my invention, I
